Application fi1edAug ust 27, 1915. Serial N 0. 47,561.

To all whom it may concern:

Be 1t known that we, CHARLES E. Dory,

' a citizen of the United States, and a resident of New York, county ofBronx, State of New York, and JOHN E. LATHROP, a citizen of the UnitedStates, and a resident of the city of Yonkers, county of Westchester,and State of New York, have invented certain new and useful Improvementsin Combined Tie-Plates and Antic'reepers, of which the following is aspecification.

Our invention relates to an improved tie plate and anti-creeper for usein railroad construction.

One of the objects of our invention is to so construct and combine atie-plate and anti-creeper that the anti-creeper will bite into the edgeof the rail base on the side opposite the gage side of the rail.

Another object of the invention is to so construct a tie-plate andanti-creeper that the wave motion of the rail will not be interferedwith, the creeper being so positioned that it may rise and fall with therail when the load passes thereover.

Another object is to so construct the anti-creeper that it will notbecome loose from the rail by reason of the changes of temperature.

Other objects will appear from the following specification and claims.

Referring to the drawing which forms a part of the specification; Figure1 is a sectional view of the rail, tie-plate, tie and anti-creeperdevice assembled in position for work. Fig. 2 is a'plan view,partlywb'roken away, of the tie-plate and anti-creeper. in

assembled position, the anti-creeper being shown partly in section. Fig.3 1s a perspec-' tive view of one form of anti-creeper device..

Fig. 4 is a perspective view of another form of anti-creeper device.Fig. 5 is a sectional View, partly broken away, similar to Fig. 1,showing a modified form of anti-creeper device in position. Fig. 6 is asectional View on line 6-6 of Fig. 1.

In the drawing, like reference characters refer to like parts.

A is a cross-tie, B the tie-plate, C the rail and D the spikes shown inthe usual position. A depression 10, rectangular in shape, is rolled onthe face of the tie-plate next to and adjoining the shoulder 11, whichshoulder is adjacent to the outside base.

-of the base 12 of the rail. The lower portion-of the depression at 13extends a short distance under the outside edge 14: of the base of therail. A depression is also rolled, as at 15, in the shoulder 11,'thetotal depth of the depression being equal to the height of the shoulderplus the depth of the depression rolled in the face of the tie-plate. Apiece of case hardened steel defined'in the art as an anti-creeper 16,is so shaped that it fits at its ends and bottom in the depression whichhas been formed in the tie-plate and shoulder. The depression measuredtransversely is greater than the width of the lower flange 18 of theanti-creeper so that a space is provided underneath-the rail for theplay of the anti-creeper.

The anti-creeper is made of an integral piece of case hardened steel andis provided with'upper and lower jaws or flanges 17 and 18 extendingfrom the same side of the vertical integral web 19. The inner side ofthe vertical integral web is provided with a series of teeth 20 cut atan acute angle with the edge of the rail, the teeth extending-oppositeto the line of direction of traffic; in other words, the line ofdirection of creep of the rail.

In Figs. 4 and 5, we have shown a modilied form of anti-creeper in whichteeth 21 formed at an acute angle with thehorizontal are also cut in thelower face of the upper flange 17. In all forms the lower flange 18 isless in width than the upper flange and its upper face is below, as at26, the under surface of the rail, so that the rail will rest on thetie-plate and not on the anticreeper device, as clearly shown in thedrawmg.

The anti-creeper device is fitted into the.

depression which is rolled in the shoulder and face of the tie-platewith the narrower flange resting on the bottom of the depression. Therail is then placed upon the tieplate and the edge of the base of therail, which is opposite the gage side of the rail, is inserted betweenthe flanges of the anticreeper device. The tie-plates with thepreviously inserted anti-creeper are then hammered into place so thatthe teeth of the anti-creeper device are embedded in the rail The sidesof the teeth which are at an acute angle extend in the line of directionof traffic. The spike holes 30 preferably 3;" square are previouslyformed in the tie- Patented Sept. 26, 1916.

plate at points on opposite sides of the rail base and the spikes l) aredriven in place as usual.

The anti-creeper extends, as shown, over the top of the base of the railand the upper surface of the creeper extends a short distance as at 25above the upper surface of the shoulder in the tie-plate.

From the above description it Will be seen that as the action on therail due to the passing load is on the gage side of the rail, thenatural tendency is for the rail to engage tightly into the teeth of thecreeper and inasmucl'i as the creeper is prevented from moving in ahorizontal direction, the rail is prevented also from having ahorizontal, movement, or in other Words, from creeping. It ill also beseen thatby the use of our in- -1 vention the Wave motion of the rail isnot impeded in any Way, as the creeper isfr'ee; to move up and downwiththe rail.

Having now described our inventiom vhatf We claim as new and desire tosecure by Let-f; ters Patent is:

1. In combination, a tie plate having ahole therein, a rail resting onthe tie plate the base of the rail covering a POItlOIl'Of the hole inthe tie plate, a U shaped anti-' creeper device fitting closely in thehole of the tie-plate, theupper leg only of the U-' shaped anti-creeperdevice having teeth formed in its under-surface, said teeth engagingWith the upper surface of the base of the rail.

2. In combination with a rail of a fixed tie plate havlng a holethereln, said holebeing provided with substantlally vertical Walls, a Ushaped anti-creeper device fitting closely in said hole and embracingthe edge of the base of the rail, said anti-creeper device being fittedto move bodily in a vertical direction only with the n'loveinent of thebase of the rail.

3. In combination with a rail, a tie plate having a hole therein, a Ushaped anticreeper device fitted in the hole in the tie plate andemln'acing the base of the rail, a lip projecting from the top surfaceof the tie plate adjacent the hole therein, one face of the lip beingcontiguous with the outer Wall of the hole in the tie plate, the base ofthe U shaped anti-creeper device engaging the said face of the lip onthe tie plate.

lyln combination, a tie plate having a hole therein, arail resting onthe tie plate, the base otthe rail opposite to the gage side only of therail covering a portion of the hole in the tie plate, a U shapedanti-creeper device fitting, closely in the hole of the tie plate, theupper leg of the U shaped anticreeper device having teeth formed in itsunder-surfa the base of the rail opposite to the gage side of the rail.

In Witness whereof we have hereunto set our hands at the borough ofBronx, city and State of New York, this 12th day of August, 1915.
